                                Recent research suggests that up to 40% of the population may carry a genetic variant affecting their ability to process B vitamins, explaining why you can't tolerate methylated B vitamins. Uncomfortable symptoms like anxiety, irritability, and headaches can result from this metabolic difference, indicating a need for a more personalized approach to supplementation.
